Question

which of the following filter system provides combining active carbon and also particle filtration?

• ultra violet (uv) filters
• reverse osmosis filters
• ceramic filters
• biosand filter

Explanation:

UV filters work on microorganisms using UV - light, reverse osmosis filters use a semi - permeable membrane for filtration, ceramic filters have pores for particle removal but may not always combine with active carbon well, and biosand filters use sand and biological processes. Reverse osmosis filters often have pre - filters that can include activated carbon for adsorption and also perform particle filtration through the RO membrane.

Answer:

Reverse Osmosis filters
